Research on the Relationship between Tunnel Segment Leakage and Large Slurry Shield Construction Parameters
(1 SHU-UTS SILC Business School, Shanghai University, Shanghai 201800; 2 SHU-SUCG Research Center for Building Industrialization, Shanghai University, Shanghai 200072; 3 Department of Civil Engineering, Shanghai University, Shanghai 200072)
Abstract Focusing on the risk control of segment leakage in large-diameter shield tunnelling, and taking the shield construction parameters as the object of study, this paper uses the multi-evaluation strategy based fusion method to extract the key features of leakage, as well as the association rule based data mining method to analyze the key feature combinations and predict segment leakage. The segment leakage rules and mechanism is obtained and a construction parameter optimization method regarding leakage control is presented. In practice, based on the measured data of large-diameter slurry shield tunnelling in soft soil in Shanghai, the segment leakage is predicted and the construction parameters are optimized, which proves that the proposed optimization method can effectively reduce the incidence of leakage events and improve construction quality.
